[Vwdiesel] return line on 84 TD jetta - ( Oldrid-- you are not reading archives )

[Nate Wall]

I have a spare injection pump and I've been hesitant
to swap onto my Jetta TD since the inner (and outter)
diameter of the return line fitting is much smaller
than the one on the pump that is on the Jetta. I
wonder if the fitting is installed at the factory to
set the internal pressure. The spare came from a
Quantum and I have a Jetta. I wonder if transverse Vs.
longitudnal engine installation makes the difference
in pump orientation having an effect on internal pump
pressure.

I wounder if I should swap the return fittings if I
switch the pumps. Is the fitting size matched to the
pump, or pump location/orientation?
